Mr. P. L. Sclater on some species of Birds from Bogota. 89 



This bird appears to be naturally placed in Dr. Cabanis' genus 

 OctJioeca, of which the type is Octhoeca oe^iantJioides {Flvvicola 

 ceiianthoides, d'Orb. Voy. ph 38, fig. 2). 



Other species belonging to this same group are Octhoeca leiicojihrys 

 {Fhiv. leucophrys, d'Orb. Voy. pi. 38, fig. 1), which the present 

 bird most resembles in colouring ; Octhoeca rujipectoralis {ibidem, 

 pi. 37, fig. 2); Octhoeca Lessoni, niihi {Tyratimdus rufipectus. Less. 

 Descr. des Mamm. et Ois. p. 296) ; Octhoeca alhidiema {Setophaya 

 alhidiema, Lafr. R. Z. 1848, p. 8), and, perhaps, Setophaga cin- 

 namomeiventris, Latr. R. Z. 1845, p. 80. The three species figured 

 by d'Orbigny are from Bolivia; the three latter, like the present, from 

 Bogota. They all offer considerable similarity in colours, and pre- 

 sent, so far as I am acquainted with them, the same structure. M. 

 de Lafresnaye has indicated the existence and affinities of this group 

 in his article in the ' Revue Zoologique,' 1848, p. 8. All d'Orbigny's 

 species inhabit his third zone of elevation, that is, above 11,000 feet 

 above the sea-level, and it is probable, therefore, that the New Gre- 

 nadian Octhoecoe are likewise from the higher regions of the Andes. 



10. EUSCARTHMUS AGILIS, Sp. nOV. 



E. supra nigro et pallido brunneo )nixfus, pennis plerumque nigris 

 brunneo marginatis : crista capitis totius medialiter nigra, late- 

 raliter autem et subius pallide brunnca : alis nigris, tectricibiis 

 rufescente terminatis, secondariis extus pallescentibus : canda 

 unicolore nigra rectricum mediarum apicibus et omnium margi- 

 nibus exterioribus pallescentibus : subtus pallide fulvo-flavidus ; 

 capitis lateribus et gutture toto albis nigro variegatis ; pec- 

 tore longitudinaliter nigro flammidato : rostro nigro, mandibula 

 inferioris bast alba : pedibus nigerrimis : tectricibus subalaribus 

 pallide fulvis . 

 Long, tota 4*6, alse 2*2, caudse 2*4 . 



This bird much resembles Euscarthmus parulus and E. albicristatus 

 in general appearance, and may, I think, be safely placed in the 

 same genus, though the bill is slightly broader, and the tail is propor- 

 tionately rather longer, and has the rectrices more graduated. 



The only example I have seen of it was transmitted to me by 

 MM. Verreaux. 



In the markings of the lower part of the body it is not unlike 

 E. p)(irulus, but the ground-colour is more yellowish, and the striae 

 less distinct on the throat and more marked on the breast. Above, 

 these two species are easily distinguishable. The present has the 

 back brown, mixed with black blotches, and not uniform cinereous- 

 olive, and the crest is shorter and differently formed, the whole of 

 the head-feathers being moderately lengthened, not a few of the 

 centre feathers only, as in the older species.
